Hello -

 

I wanted to upgrade ACR 13.4 to version 14
Unfortunately my Mac was working under Mac OS Mojave (and therefore impossible to install ACR version 14).
So I downloaded and installed MAC OS Monterey 12.0.1
Since then, several DNG files do not want to open and I have the following message

"Could not complete your request because Photoshop does not recognize this type of file."

So I downloaded and installed the latest version of Photoshop 23.0.0 (Photoshop CC2022).

But it still doesn't work, I still get the same error message.


What should I do (I already did a reset and threw the "preferences" in the trash).

Tahnk you.

Hello Jeffrey -

 

Sure… But since they are DNG/RAW files they  are quite big (very huge, eg. ± 800MB for 4 files)

How to do that?  Thx

When I try to upload one of these "problematic" files, I get the following answer:

"

Correct the highlighted errors and try again.

  • The attachment's l1000307.dng content type (image/x-adobe-dng) does not match its file extension and has been removed.
    The attachment's l1000304.dng content type (image/x-adobe-dng) does not match its file extension and has been removed.

".

 

NB. I'm sure they are .DNG files!!!

For some PSD file  —>  "Could not open “L1000596_Retouch.psd” because it is not a valid Photoshop document."

 

My external SSD disk haven't problem I checked it.

Any relevant help will be much appreciate.

Have a good day…
